Abstract (en)
[origin: EP2424270A1] A loudspeaker device (200) is presented which includes a zeolite material (100) comprising zeolite particles (102) having a silicon to aluminum mass ratio of at least 200. For an increased pore fraction of pores with a diameter in a range between 0.7 micrometer and 30 micrometer shows an increased shift of the resonance frequency down to lower frequencies has been observed.
